While one embodiment of the invention vvhas been specifically describedand illustrated in which the Voperated plunger moves a distance doublethat of the operating cross head, the inventionlis not limited'to suchconstruction. Y f

Various modifications of the invention may be made in which theoperatedplungermay move a distance greater'thanv orless than double that throughwhich 4the operating A cross head moves.

All of theseV modilications are held to be within theipurview of theinvention.
